A frequent question among student is “difference between Digital to Analog converter and Analog to digital converter”. There are many views of solutions or this question. Here i am going to dedicate a accurate solution for this million dolor question.
Our Computer’s sound circuitry boils down to two converters, they are a Digital to Analog Converter(DAC) and an Analog to Digital Converter (ADC). Analog refers to natural things with constant motion: ocean waves, for instance, and waves of sound. Digital refers to numbers: static entities that never change, like the 1s and 0s that are encoded on your audio CDs.
Since PCs understand only numbers, the sound card’s two converters constantly translate between the two formats. The better quality the converter, the better the recreation of the horn player’s solo in the studio. It works like this: the horn player sends sound waves through the air, and the engineer records the sound to tape using streams of magnetic waves: The CD factory’s Analog to Digital converter converts the tape’s waves into numbers and stores them on a CD.
Your PC’s Digital to Analog converter reads the numbers on the CD and converts the sound to waves of electricity, which it sends to your speakers. The speakers vibrate, recreating the horn player’s original sound waves. Your PC’s Analog to Digital converter lets you record through a microphone , or even from a radio or TV.
